EARTH-AUGER.

SPIEICIPICAI'ION forming pari: of Letters Patent N6. 351,703, datedOotol'oer 26, 1886. Application filed Jannn-ry 12, 1886. Serial N0.188,329. (N model.)

T0 all whom z't mag concern:

Be 112 known that we, JOHN J UNGBAUER and "GILBERT JULIUS SEIELSTAD,citizens of the United States,residing at-Jackson, in the count y of Jackson and State of Minnesota, have invented certain new and usefulImprovements in Earth-Augers; and we d0 declare the following t0 be afull, clea1, and exact description of the invenbion, such as Will enableothers skilled in the art; 110 which it appertains t0 make and use theSame, reference being had to the accompanyingdrawings, and t0 bhe lettrsand figures of referenee marked thereon, which form a, part of thisspeeifieation.

This invention relates to augers 0f that dass designed t0 bore int0 thee2uth, andparbicularly adapted for use in boring weUs in sectionsalbounding in sand and gravel; and it consists in details ofeonstruction and Combinations of p&rts, as fully shown, and hereinafter1n0re parbicularly pointed out and claimed.

In the dmwings, Figure 1 1's a side elemtion 0f our improved auger, thebottom being shown swung open in dotted 1ines. Fig. 2 is a verticalsection on Ehe linex x, Fig. 3. Fig. 3is a bottom plan view. Fig. 4 is aplan view of the bottom debaehed, showing the aut- 0ff elosed. Fig. 51's a similar view.

Ihe auger proper consists of 1;he shell A, bottorn B, provided wibh thebits 01;" scoops O, and shafb l). 'Ihe she1l is cylindrical in'form, andnmy be of any desired length and diameter and composed 0f snitablemateria-I, sheel: metal being preferred, owing to its strengbh anddurability as compared with the bulk of material. 'Ihe botton1 is hingedto 0ne side of the she1l ab (a, und opposite the hinge its is providedwith an elongated opening, b.

A V-shaped porbion 0f meta1 is removed from 4 dianiet-rie opposite edges0f the bottom, forming openings c, which extend nearly t0 the center 0fthe bottom. A portion Of the bottom bordering on corresponding sides ofthe openings c is bent downward, forming 1ips c, t0 which Ehe bits Garesecured in any suitable manner by either bolts 01 rivets. 'Ihebits havethe lower'portion 0f their inner ends exbended towar'd eaeh other,forming wings o and their outer ends cT1rved upward, as shown ab Ihecenter 0f the bottom is perforated, and this perforation d issurrounded. by an recut-off. The eenter 01' Ehe eut-off is perforated t0coincide with the opening d intflmbottom. A re-enforcing piece surroundsbhis opening and has an angular opening,f. The shafb I) passes centrallythrough the shell and is held therein by braces G and H. The lower en(1of the shaft: projects-through theopening din the bottom, and thatportion coinciding with the openingf in the re-en forcingpiece is madeto correspond therewith.

In operation, the shafb.being turned in the directzion of the arrows,Figs. 3 and 5, the ent- 0ff will disclose the opening 0 and permit theborings to enter the.shell. 'Ihe ]atter being full, a reverse movement;0f the shafb (indicated by the arrow in Fig. 4) will elose the botton1and prevenb the dirb, &0., from falling 0ub qf the Shell during itsascent, as will be readily comprehended.

T0 prevent v6rbical displacement 0f the shaffi, in 1's provided withstops g and h, respecbively, to engage With the braees G and II. A r0d,I, journaled to one si de 0f the Shell has an upper bearing in lshebraee G and a lower bearing in a bracket, J,attached to the side 0f theshell. 'Ihe lower end of the 1 0d is flattened and has s.houldersformed011 each side. This fiattened portion passes throngh the opening Z), andby giving the 1od a parlial turn by means 0f bhe crank j, the shoulders13 Will be p10j ected beyond the sides 0f theopening and lock the bottomin position. 'l0 release the bottom and permit its swinging open, assl1-own in dotted lines, Fig. 1, the rod is turned ti1l the fiattenedportion registers with the opening b,when the bottom is free and willopen, asjust deseribe The shafb D 1nay have sections D coupled theretoin any well-known manner.

Having thus deseribed my invention, what' I claim, and desire t0 secureby Letters Patent, is-
